The temperature roller-coaster ride will continue into St. Patrick's Day for the Philadelphia area.
After a mild Satuday, temperatures failed to climb out of the 40s Sunday. Even colder weather is on tap for Monday as a snowstorm grazes the city.
Snow will be seen around the city Monday morning followed by a dry, but chilly afternoon.
"It's the typical roller-coaster ride of March," AccuWeather.com Senior Meteorologist Dave Dombek said. "March is notorious for huge temperature swings."
A snowstorm will graze the area Sunday night and early Monday but the heaviest snow is likely to stay south of the city. However, it will be chilly and those planning to be outside and celebrate St. Patrick's Day on Monday should continue to check with AccuWeather for updates.
Philly's normal temperatures this time of year are highs in the lower 50s during the day, dropping into the lower 30s at night.
